Dinner was almost ready ...
Me: Meg, dinner's almost ready. You and Nikki have 2 more minutes to play, then she'll have to go home because it'll be dinner, baths and bedtime.
Meg: But we haven't gone swimming yet!
Me: It's not my fault you chose Polly Pockets over swimming.
I finished up dinner preparations ...
Me: Okay, dinner's ready.
Megan came into the kitchen with Nikki, who proceeded to take off her cover-up.
Megan: Mom, we're just gonna' go for a quick swim.
Me: Uh, no you're not. Dinner is ready. That means that Nikki has to go home.
Megan: Okay, but after dinner could she come back for a night swim?
Me: Meh-gaan. Dinner, baths, bedtime, remember?!
Nikki: Okay Megan, let's just play house instead.
Nice to know that my kids aren't the only kids who don't listen to me.
